Alignment Problems:Changes in posture or poor body mechanics may bring about spinal and lower limb alignment problems and muscle shortening, therefore causing other muscles to be misused and become painful. Faulty alignment is often treated from the spine or core in an outward direction. This is a valid approach but the foundations (i.e. the feet) of a structure must be carefully examined and modified to achieve correct alignment and posture. Custom orthotics prevent excessive internal and/or external rotation of the lower limb and hence correct chronic postural faults.
